Thackery Washers

[g32turbo]

I'm just about to bolt my twin 45 DCOE's to the new manifold using the studs and Thackery washers supplied with the manifold. Should I be looking for a particular torque or compression of the washers as a guide to how tight to take the nyloc nuts. I believe that there is another option of using cup washers and rubber spacers but since the Thackery washers were supplied I might as well use them.

Not torque AFAICR but I think it's something like a 20-40thou feeler guage between the coils of the washer. To be honest Mishab washers are much better & it's a damn long time since I worked on a car that didn't have Mishabs.

Agree with tr7v8, you'd be better ditching the Thackery washers in favour of the cup washers and rubber spacers.

I bolt mine up so there is about a 2-3mm gap. Just make sure all the gaps are the same.

Thackery washers have had there day they are also prone to fracture,Graham Bell is on the money use the cups & rubbers far more reliable.

Oops, I didn't read the thread properly, I was under the impression that Thackery washers were the rubber type with the cups which is what I use.

Then you are using the Pukka ones already Falsemob
